RULE.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed May 17,1906. Serial No. 317,303-

To all whom, it natty concern:

Be it known that I, HIRAM D. HAGERMAN,

a subject of the King of Great Britain, and a.

resident of Houlton, in the county of Aroostook and State of Maine, have invented a new and Improved Rule, of which the following is a full, clear, and exact description.

This invention is an improvement in rules, particularly relating to those used by machinists, having, among other objects, the provision of a device of this character with a suitable cooperative scriber incased between the hinged members thereof forming a con venient adjunct to the rule of a mechanic and enabling him to have these necessary devices always at hand without impairing the effectiveness of either.

Generally stated, the invention consists of an ordinary two-foot or other desired length ruler having the outer hinged members grooved on their opposed edges, with a metal scabbard secured therein to one of the members. In the scabbard is inserted when not in use a scriber adapted to fit it and be held from accidental displacement by means preferably carried by the scabbard.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improved combined rule and scriber. Fig. 2 is an edge view of the rule with a hinged member thereof open to more clearly disclose the nature of my improvement. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 1. Fig. 4 is a plan view of the scriber; and Fig. 5 is a fragmentary detail view of the outer ends of the scabb ard and scriber, showing the spring tongue for holding the scriber from accidental displacement.

Referring to the drawing figures, the numeral 1 indicates an ordinary two-foot rule, comprising members 2- and 3, pivoted together at 4 to swing outwardly in the same plane, with members 5 and 6 respectively hinged to their free ends to lie flat against them when closed. The opposed edges of the members 5 and 6 are grooved longitudinally for almost their entire length, as at 7,

leaving a shoulder 8 on each member, from which extends a conical recess 9, as shown in dotted lines in Fig. 1, forming a prolongation of the grooves and adapted to contain a scriber-point.

Secured in the groove to the member 6 of the rule, by means of rivets 10 passing transversely through it parallel to its faces, is a metal scabbard 11, abutting against the shoulders 8 and passing to within a short distance of the end of the rule. This scabbard is of circular cross-section and is provided at its outer end with a spring-tongue 12, which yieldingly presses on a steel scriber 13 when the latter is inserted therein. The scriber has a tapered point of hardened steel 14, which is seated in the recess 9 when in place, and a head 15, preferably knurled, for withdrawing it from the scabbard when desired to put it to use. The milled head 15 is of the same diameter as the external diameter of the scabbard and is equal in length to that part of the grooves 7 not filled by the scabbard in order that it will neatly fit the same and not project beyond the rule when in place.

It should be noted that the scabbard 11 not only serves as a casing for containing the scriber, but also acts as a key to hold the members 5 and 6 together when closed,which is an important cooperative action between the two devices.

The precise embodiment of my invention is not material, provided its essential characteristics are employed as pointed out in the invention as claimed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a rule, lunged members grooved 011 their opposing edges, a conical recess in the edges of the members forming a prolongation 3. A rule comprising hinged members, a scabbard secured between the opposing edges of said members, and a spring-tongue at the outer end of the scabbard for yieldingly pressing on an auxiliary tool inserted therein,

4. A rule comprising hinged members grooved on their opposing edges, a cylindrical'metal Scabbard secured in a groove of one of the members, and a tongue at the [o outerend of the Scabbard adapted to yieldingly engage an auxiliary device inserted therein.

In testimony whereof I have signed my name to this specification in the presence of' two subscribing Witnesses.

HIRAM D. HAGERMAN.
